Module Dolmen_intf.TokSource

Interface for token descriptions This doe snot define an interface for token descriptions but rather defines a type for token description, that will then be used by others interfaces.

Sourcetype descr = {
  1. article : string;
  2. kind : string;
  3. lexeme : string;
  4. hint : string option;
}

The description fo a token, to be used when pretty-printing error messages. The idea is to be able to ouput a message such as "the parser expetced something, but got %article %kind: '%lexeme'"
